CMOS/GPNV Checksum Bad Error

[Jim]

After an attempt to flash my BIOS with Intel Express BIOS update I get the
following error,
CMOS/GPNV Checksum Error
Press F1 to run SETUP
Intel support says to reset the CMOS settings after the upgrade to custom
defaults to map the changes between the two BIOS versions. I tried but does
not work When I try to change any settings and reboot I get the same
CHECKSUM error.
Another "workaround" I found was to exit CMOS and discard changes which
gives me the following error,
INTEL BOOT AGENT VERSION 4.0.19
PXE -E61 MEDIA TEST FAILURE CHECK CABLE
PXE-MOF EXITING INTEL PXE ROM
BOOT FAILURE SYSTEM HALTED.
When I manually shut down and rebooted after this message I could get
Windows to start. I then got the BIOS program which says the update failed.
I did not write the original CMOS settings down because I thought loading
custom default settings would work.
The OS will load but I get the same cycle of error messages beforehand
except
for the failed BIOS update message.
I hope I'm not out of luck on this one.
TIA for any help.

The Intel BIOS Express program should have backed up your previous
CMOS flash version. If possible, restore the previous version and
then select default for all settings. Perhaps that's what Intel
support was trying to tell you.

Flashing the BIOS can sometimes lead to errors or a situation where
the machine won't boot at all. In your case it appears that an error
occurred during the flash process. You may wind up having to order a
new cmos chip from Intel. Without knowing your particular board -
some of the newer cmos chips are surface mounted to the MB. If that's
the way your board is designed, then you will have to replace the
entire motherboard.

How can I restore the previous version? The only way to get out of CMOS set
up is to exit without changes. It will not let me save the changes. Also, I
could go into BIOS recovery mode but I can't seem to find the right BIOS
version for my motherboard, which is what I think happened in the first
place, Intel pointed me to the wrong BIOS version.

If you did indeed flash with the wrong bios, you had better hope that you
are still able to flash with the correct one - when you find it! You bios
chip may be damaged beyond use and prevent a reflash.

Well I know that. I'm looking for solutions to my problem. If you read the
post can you come up with a good answer?

 

[Richard Urban]

Try to flash with the correct file. If it works fine. If not, either get a
new chip or a new motherboard.

What else do you want me to say? There is nothing else!

Use the CLEAR CMOS jumper on the motherboard.

 

[Jim]

You need to say nothing because your advice is worth nothing much like most
of your posts. One line answers and a bad attitude are best kept to
yourself, because you help no one.

Thanks, that was the answer I needed. Working just fine now.
